The Pebble is a smartwatch developed by Pebble Technology and released in 2013 that was funded by raising money via the crowd funding platform Kickstarter. After raising venture capital for the product under their former name inPulse, the company failed to attract traditional investors under their new brand name, so they requested crowd funding in April 2012. At the end of the funding, Pebble became the second, most highly crowd-funded project to date with $10,266,844 pledged by 68,928 people. As of July 4th 2013, Pebble has sold over 85,000 units. The watch has a 1.26-inch 144 × 168 pixel black and white ultra low power "transflective LCD" made by Sharp (described as "ePaper" with backlight, a vibrating motor, a magnetometer, ambient light sensors and a three-axis accelerometer. It will communicate with an Android or iOS device using Bluetooth 2.1 but includes support for Bluetooth 4.0 (Bluetooth Low Energy) for a later update when more phones support it. The battery was reported in April 2012 to last seven days. Based on feedback from Kickstarter backers, the developers added water-resistance to the list of features. The watch is charged using a modified USB-cable that attaches magnetically to the watch so as not to compromise water resistance.The Pebble was slated to ship with apps pre-installed, including a cycling app to measure speed, distance and pace through GPS, and a golf rangefinderapp that supports more than 25,000 courses. These apps use data received from a connected phone for distance, speed and range information. More apps will be downloadable from the phone, and an SDK will be freely available. Not all apps will be installed when the watch ships but CEO Eric Migicovsky announced on January 9, 2013 that there will be updates for the watch's OS (which is based on FreeRTOS) every 2–3 weeks until all features are added.
